Good afternoon
I would like to ask if anyone is aware of any BS standard that provides any guidelines on how to size a generator set
We currently have a big hotel that has life safety systems (fire fighting lift, smoke ventilation, sprinkler system...etc)
Is there anything in the British Standards about this or we go by the common sense?
At this stage I have to say that in the past I have heard the following rule:
'It has to be able to start the biggest motor (highest starting current) while everything else is operating'
However in this very project its the first time the sprinkler subcontractor asked us to size the generator based on 1 sprinkler pump at locked rotor and the standby pump starting. So after this if I add all the rest (smoke vent panel, fire fighting lifts, car park smoke vent etc) this leads to a huge total current so I am starting this discussion in case someone know of any official guidelines or any other help is appreciated
Thanks
